The Amino Acid Sequence of Human Chorionic Gonadotropin

P-234: Expression of Human Chorionic Gonadotropin (hCG) Hormone Using Chinese Hamster Ovary Cells

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

Identification and Confirmatory Method for Human Chorionic Gonadotropin (hCG) using HPLC/MS/MS Analysis

Isolation and amino acid sequence of the alpha-subunit of follicle-stimulating hormone from equine pituitary glands.

Six hundred milligrams of follicle-stimulating hormone (FSH), containing 110 NIH-FSH-S1 units/mg, was isolated from 9 kg of equine pituitary glands. The equine FSH was dissociated into alpha- and beta-subunits. A tentative amino acid sequence of the alpha-subunit was determined. The alpha-subunit contained 82 amino acids. The equine FSH-alpha is shorter by 10 to 14 amino acids at the NH2 termin...

Effect of Adding Human Chorionic Gonadotropin to The Endometrial Preparation Protocol in Frozen Embryo Transfer Cycles

O-32: Effects of Intrauterine Injection of Recombinant Human Chorionic Gonadotropin before Embryo Transfer on Outcome of In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Randomized Clinical Trial

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...
